Roger Scruton: "The object of musical hearing is organised by metaphors of space and movement that correspond to no material realities. Music goes up and down, it leads and follows; it is dense, translucent, heavy, light; it encounters obstacles and crashes through them, and sometimes it comes to an end which is the end of everything. Those metaphors, and the order derived from them, are shared by all musical people. The order that we hear is an order that we – the musical public – hear, when we hear these sounds as music. And although there is, at any moment, an indefinite number of ways in which a melodic line or a chord sequence can continue without sounding wrong, the ideal in our tradition has been of an uninterrupted sense of necessity – each melodic and harmonic step following as though by logic from its predecessor, and yet with complete freedom. ... When we hear tones we are also hearing sounds; but we are hearing in those sounds movement, organisation and gravitational forces in a one-dimensional musical space. That is the fundamental musical experience, the experience that causes us to hear one note as moving on from another, answering another, attracted to or repelled by another. It is what enables us to hear tension and release, beginnings and endings, goals and starting points. It is at the root of the art of music as we have known it, since it is what gives music its fundamental nature as an art of motion, which grips us and takes us with it in a space of its own. We are moved by music because music moves."
